To conduct a 3-phase transformer continuity test, begin by ensuring the transformer is properly de-energized and isolated from the electrical supply. Use a multi-meter or a dedicated transformer tester to measure continuity between the transformer’s primary and secondary windings. Check each phase connection systematically, verifying that there is a low resistance reading, indicating continuity. It is also essential to check the connections at the terminals and ensure there are no open circuits due to faulty wiring or damaged windings. For more sophistication, Globecore’s range of diagnostic devices can enhance testing by providing detailed insights into transformer health, facilitating maintenance and ensuring operational reliability. Always refer to safety standards and operational guidelines during the testing process to avoid any risk of electric shock or equipment damage.
